IDTechEx’s new report, “Electric Vehicles in Construction 2023-2043,” shows that there is a battery price tipping point, under which it will be cheaper over the vehicle lifetime to operate an EV. Selecting the right chemistry will be imperative for getting a low enough vehicle price. So why is a clear dichotomy seen between the batteries being deployed in China compared to Europe?Electric vehicles in construction are an emerging market. IDTechEx has built a database of more than 100 example makes and models across seven different construction-vehicle categories: mini excavators, excavators (&gt;6 tonnes), compact loaders, backhoe loaders, wheel loaders, telehandlers, and mobile cranes. However, with lots of vehicles yet to be released, only 49 database entries have confirmed chemistry information.Europe and China have more established markets for electric construction vehicles, which makes it possible to draw some conclusions about battery-chemistry trends from OEMs in these regions. What is obvious at this early stage is that Europe heavily favors NMC (nickel manganese cobalt) lithium-ion batteries, while China has chiefly chosen LFP (lithium iron phosphate) batteries.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzAxMTc1Nzg4MTQ4LXNhZSAxLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 300px;" class="fr-fic fr-dib">Six of the top 10 largest construction companies have either a prototype or concept electric mini-excavator available in 2023. Image credit: IDTechEX.Battery requirements in construction vehicles So, why would one select NMC, LFP or even lead acid? A battery that electrifies construction equipment needs to have huge capacity and low cost. Some of these machines are extremely large and usually require concrete counterbalances to handle the massive loads they encounter. What this means for electrification is that battery weight isn’t much of an issue.Power density also is not a priority. Unlike electric cars, construction vehicles do not tend to have large power-demand spikes and are more likely to operate at a steady rate for a long time. As an example, some early Tesla Model S EVs had a 60kWh battery and a 210kW motor power, meaning its battery must be able to deliver a peak of 3.5C (power divided by capacity), typical for road cars and why they tend to favor power-dense chemistries like NMC.By contrast, the Volvo L25 electric compact loader has a battery capacity of 40kWh and a maximum motor power of 36kW, so the battery is only required to discharge at a maximum of 0.9C, well below road-car expectations.The same is true when considering the larger machines. The XCMG XE270E is a 27-tonne excavator with a battery capacity of 525kWh, but its motor is a paltry 140kW (~0.27C). In fact, research in the IDTechEx report shows that the vast majority of electric construction vehicles have a peak discharge requirement of less than 1C, with one-quarter of vehicles requiring less than 0.25C peak discharge.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzAxMTc1OTU1MjM4LWJhdHRlciBzYWUgMi5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 300px;" class="fr-fic fr-dib">Battery requirements vary depending on vehicle sizing and applications. Image credit: IDTechEXA low peak discharge requirement can be fulfilled by lead-acid batteries, which is likely why it was explored in the early days of construction electrification. The European examples that used lead acid were mainly from the mid-2010s, when lithium-ion technologies were still scaling and were much more expensive than lead acid. However, these vehicles were seriously limited, with low endurance and slow recharge times. Lead acid was replaced with lithium-ion once the newer technology became more financially viable.Both NMC and LFP offer the required performance for construction, coping with the peak discharge requirements and having high enough volumetric and gravimetric densities to fit in the machines. Speaking broadly, NMC tends to be a higher-performance battery than LFP, with better energy and power densities but coming at a premium. It would make sense then for the industry to select LFP. It offers all the needed performance while helping minimize the cost premium of building an electric vehicle – the number one priority for electric construction vehicles. So why does the European market mostly use NMC?Choosing between NMC and LFP The best explanation for why NMC dominates in Europe while LFP has taken off in China is a case of availability. Thus far, most of the construction-EV development in Europe has used battery-pack suppliers such as Northvolt, Forsee and Volta, and most of their products use NMC.IDTechEx’s research finds that more than 75% of the offerings from European and North American pack manufacturers use NMC. These companies have been supplying a range of industries, including heavy-duty road vehicles such as buses and trucks. These vehicles require high peak power to deal with acceleration events, hills, etc. and are better suited to NMC. But with battery pricing being a key factor in the success of electric construction vehicles, increased LFP uptake is likely in the future.Meanwhile, China already has a good supply of LFP solutions. As the country’s vehicle fleet has shifted to more electric vehicles, the domestic auto industry needed a more affordable solution that offered acceptable energy density (for an acceptable vehicle range). China’s electric construction industry has been able to build large batteries relatively quickly and deploy some huge machines, such as the already-referenced XCMG XE270E. By contrast, European and North American EV markets have focused on maximizing vehicle range, normally opting for the more expensive NMC chemistry, anticipating that their consumers will be more comfortable with the additional cost.Unfortunately, there is not much data concerning which battery chemistries North American or APAC-based OEMs favor. This is mostly because OEMs in these regions are not as far along in their electrification journeys. North America is a prime example. Caterpillar and John Deere have made a recent push with electric construction vehicles showcased at Bauma 2022, CES 2023 and CONEXPO 2023. However, these machines are still some years away from production, and battery chemistries are yet to be confirmed. An educated guess, however, would suggest that Caterpillar likely will use NMC for reasons similar to those driving decisions at European OEMs.<h3>Is sodium-ion a future candidate?</h3>Another possible contender for the construction industry is sodium-ion, an emerging chemistry that does not have an established market yet. The key thing to know is that sodium-based solutions can be produced at lower costs than lithium ones, but they will not offer the same performance capabilities. In this respect, the batteries have the same trade-offs as LFP batteries.The issue is that sodium-ion is not yet a scaled solution, so it is more expensive than both LFP and NMC while having worse performance. Sodium, therefore, does not make sense in the construction industry for the time being. However, if it can be scaled and then deliver the promised price reduction, sodium-ion could be a prime match for the needs of this nuanced market.The construction EV industry is still nascent, with few vehicles in series production. However, if recent activity and announcements are to be believed, the number of machines available in the next few years is going to explode. In IDTechEx’s report, a 10-year CAGR of 37% is forecasted, with the electric construction machine industry growing to a value of US$150 billion in 2043. All this growth will give rise to significant battery demand. Whether the solution ends up being NMC, LFP or perhaps even Na-ion, the evolution of this industry is underway and accelerating fast.Dr. James Jeffs, senior technology analyst at IDTechEx, wrote this research summary submitted to SAE Media.

Battery chemistries for construction EVs

ETH Zurich researchers deployed an autonomous excavator, called HEAP, to build a six metre-high and sixty-five-metre-long dry-stone wall. The wall is embedded in a digitally planned and autonomously excavated landscape and park.<iframe width="640" height="360" src="https://www.youtube.com/embed/P7wmotyKgXc?&amp;wmode=opaque&amp;enablejsapi=1&amp;origin=https://www.wevolver.com" frameborder="0" allowfullscreen="" class="fr-draggable" data-lf-form-tracking-inspected-kn9eq4roawkarlvp="true" data-lf-yt-playback-inspected-kn9eq4roawkarlvp="true" data-lf-vimeo-playback-inspected-kn9eq4roawkarlvp="true"></iframe>Video: ETH Zurich / Girts ApskalnsThe team of researchers included: Gramazio Kohler Research, the Robotics Systems Lab, Vision for Robotics Lab, and the Chair of Landscape Architecture. They developed this innovative design application as part of the National Centre of Competence in Research for Digital Fabrication (NCCR dfab).Using sensors, the excavator can autonomously draw a 3D map of the construction site and localise existing building blocks and stones for the wall’s construction. Specifically designed tools and machine vision approaches enable the excavator to scan and grab large stones in its immediate environment. It can also register their approximate weight as well as their centre of gravity. An algorithm determines the best position for each stone, and the excavator then conducts the task itself by placing the stones in the desired location. The autonomous machine can place 20 to 30 stones in a single consignment – about as many as one delivery could supply.<hr><h2 id="isPasted">Reference &nbsp; &nbsp; &nbsp; &nbsp;</h2>Johns RL, Wermelinger M, Mascaro R, Jud D, Hurkxkens I, Vasey L, Chli M, Gramazio F, Kohler M, Hutter M: A framework for robotic excavation and dry stone construction using on-site materials, Science Robotics, 22 November 2023, DOI: <a href="https://doi.org/10.1126/scirobotics.abp9758" target="_blank">external page10.1126/scirobotics.abp9758</a>

Under the stewardship of Karen Scrivener, head of EPFL's <a href="https://www.epfl.ch/labs/lmc/" target="_blank">Laboratory of Construction Materials&nbsp;</a>at the School of Engineering, a team of researchers has been wrestling with the environmental implications of concrete, a material produced at an astonishing four tonnes annually for every human on Earth. The challenge? Cement, concrete's binding component, accounts for a significant 8% of worldwide emissions. And clinker, the key component in cement, is extremely carbon intensive, making up 90% of overall cement emissions in the fabrication of concrete. The solution? LC3, short for Limestone Calcined Clay Cement. Not just an alternative, LC3 offers the potential for enhanced durability, cost-efficiency, and a significant reduction in emissions. Finding a solution to reduce the climate impacts of concrete while providing for the needs of growing economies is vital.<h2>LC3: the innovation changing the cement industry</h2>LC3 addresses both sources of carbon emissions from making clinker. First, it replaces half of the clinker with calcined clay and ground limestone, neither of which release carbon when heated the way limestone does. Second, the clay is heated to a much lower temperature, which reduces the amount of fuel required and resulting emissions. With lower temperatures it is also more feasible to switch to cleaner energy sources such as electricity than it is for making clinker. LC3 can reduce CO2 emissions around 40% compared with conventional cement by replacing half of the clinker.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1700476042742-download.jfif" style="width: 766px;" class="fr-fic fr-dib">LC3 cuts the amount of carbon-intensive clinker required in cement, significantly reducing overall emissions. © 2023 Projet LC3 / Conception par Zoï Environment NetworkLC3 is functional, too. It is less pervious to water and salt, so it makes concrete roads and bridges more durable and longer lasting, reducing the cost and disruption of replacement. Since it requires less energy to make and uses widely available clay it can be produced at a lower cost, up to 25% lower.<h2>Cutting 500 million tons of CO2 by 2030</h2>LC3 is already growing rapidly and is currently being produced in a number of plants around the world. For each ton of calcined clay produced, we are saving 600 kilograms of CO2. By the end of 2023 LC3 will have already saved around 15 million tons of CO2. By 2025 it is expected that LC3 will have saved 45 million tons. If the cement industry widely adopts the use of LC3, it can help prevent up to 500 million tons of CO2 emissions by 2030.Many of the leading cement producers are in the process of adopting calcined clay cement. Holcim, for example, announced in January 2023 the launch of operations at a plant in France that will deliver up to 500,000 tons of low-carbon cement per year. Argos Cementos in Columbia produce 2.3 million tons of LC3 cement a year, which is already being used locally in the construction of roads, tunnels and buildings.<h2>The future of cement in the Global South</h2>In the coming years and decades, the majority of new construction worldwide will occur in the Global South — particularly in Africa, where the population is expected to increase by 1 billion by 2050. That means a lot of cement.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1700476068290-download+%281%29.jfif" style="width: 766px;" class="fr-fic fr-dib">The Global South, particularly Africa and Asia, will require huge quanitities of cement in the future. © 2023 Projet LC3 / Conception par Zoï EnvironmentAfrica has the world’s fastest-growing population, yet suitable limestone to manufacture clinker is scarcely available on the continent. Today, the costly import of clinker has a direct impact on costs. It causes affordability issues for housing and infrastructure. Fortunately, clays are the weathering products of common rock types. As a result, they are widely available in most geological settings. Clays containing kaolinite, the most suitable clay types for LC3, are abundantly available across Africa.By adopting LC3 technology and replacing a substantial part of clinker with local resources, African countries and those across the Global South can create world-class local industries and reap the economic and employment benefits. This will reduce the need to import clinker with foreign currency and allow the construction of housing and infrastructure at lower costs, all while limiting CO2 emissions.<h2>A reimagined concrete value chain</h2>Reducing the amount of clinker in cement reduces emissions in the production of cement, but there are many additional strategies if we look across the entire value chain of concrete. By improving the energy efficiency of plants and using alternative fuels such as waste fuels, we can further reduce CO2 from the production of clinker. By more carefully selecting the aggregate size gradations there is less void space for the cement paste to fill, saving on cement cost and emissions.We can also improve the design and efficiency of concrete used in structures and buildings. The Global Cement and Concrete Association estimates that this could save 22% of concrete while also cutting costs. Finally, adapting certain design elements and increasing efficiency as well as recycling materials will further reduce the impact of concrete on the climate. If all of these strategies are combined, we can achieve up to 80% reduction in the emissions from cement and concrete using today’s technologies.To reach this goal, stakeholders across the industry must work together, from the cement and concrete producers, contractors and trade partner, design team and owners. Changing existing practices and gaining momentum for an industry-wide shift requires diligence and perseverance. There needs to be strong willingness from both the private and public sectors to work together to facilitate a transition to net zero emissions in construction while providing solutions for sustainable growth. Now more than ever we need public-private cooperation to see real solutions scale.

A new material developed at EPFL could change how we make cement forever — and cut 500 million tons of emissions by 2030.

The future of construction with more sustainable cement

Concrete is the most widely used building material worldwide, providing the foundation of our modern society’s infrastructure. It is partially recyclable and can even absorb CO2 from the atmosphere during the curing process. However, the amount of CO2 released during the manufacturing process far exceeds the amount that can be reabsorbed later. This is why the concrete industry generates around eight percent of global CO2 emissions – more than the aviation and shipping industry combined. Franco Zunino, a senior scientist at the Institute for Building Materials at ETH Zurich, wants to alter the formulation of concrete by adopting an “ultra-green concrete” approach.<h2>The ideal concrete</h2>Concrete consists of a mixture of cement, aggregates and water. Traditional cement is composed of about 95 percent clinker and five percent gypsum. To produce cement, limestone and clay are burned into clinker in a kiln heated to 1,450°Celsius, which inevitably releases CO2 due to the chemical decomposition of limestone. The huge amount of energy required by the kiln further worsens cement’s carbon footprint.EPFL has already launched its Limestone Calcined Clay Cements (LC3) project, in which Zunino is actively involved and which has set a new standard in cement production. It has developed a cement formulation using 50 percent clinker and a combination of calcined clay and limestone that has cut CO2 emissions by around 40 percent. However, improving the formulation of concrete can bring about a significant increase in these environmental benefits. This is where Franco Zunino’s UGC project at the ETH-Department of Civil, Environmental and Geomatic Engineering (D-BAUG) comes in.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1699804179857-image.imageformat.1286.1895314494.png" style="width: 766px;" class="fr-fic fr-dib">Three LC3-based concretes with varying amounts of cement. As the cement content in the concrete mix decreases, the compressive strength increases. (Photograph: Franco Zunino)Franco Zunino pursues a two-fold strategy for the new green concrete: first, reducing the clinker content, i.e. the amount of clinker per unit of cement; second, lowering the ratio of cement in the concrete. This dual strategy offers flexibility in tailoring low-carbon concrete compositions to individual markets. “The ideal would be to implement both at the same time; but the individual components are independent of each other. In some markets, it may be difficult to implement both aspects of the dual strategy, as production capacity and infrastructure need to be put in place. However, it is possible to implement at least one of them and still save reduce CO2&nbsp;emissions,” Franco Zunino explains.Calculations by Zunino and his team have shown that the CO2 emissions of Ultra Green Concrete can be reduced from 300 kg per cubic metre to about 80–100 kg per cubic metre. Depending on the application, up to two-thirds of CO2 emissions could be consequently saved without compromising material performance. Although the researcher emphasises that there is no such thing as inherently climate-neutral or carbon-negative concrete, he believes there are no excuses for the industrialised world not to adopt this new and more sustainable building material right away.<h2>More cost-effective than traditional concrete</h2>One reason for the reluctance might be that the concrete industry is not particularly innovative. Concrete has proven to be highly successful due to being cost-effective, safe and user-friendly. According to Zunino, “green concrete” could be even cheaper than conventional concrete. The proportion of expensive components is lower, while the quality and thus price of the concrete remain the same. This creates financial incentives for using more environmentally friendly material.Safety aspects are also important, of course. Franco Zunino comments: “Anyone who builds a house wants to use a material that insures it will stand for a hundred years. But we have to ask ourselves whether this really makes sense in view of the enormous CO2 emissions involved. Could we instead use a material that meets the structure’s required life cycle but emits significantly less CO2? In a climate-crisis scenario, one tonne of CO2 saved today is more valuable than the same tonne saved in 50 years.”<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1699804212720-image.imageformat.1286.1672952278.jpg" style="width: 300px;" class="fr-fic fr-dib">From lab test to prototype: test cylinders of LC3 cement.

There are currently about seven large-scale cement plants worldwide producing cement using the LC3 approach. Franco Zunino expects that number to exceed 40 in the coming years. “Demand for concrete will increase in the future. We can offer assistance by developing improved concrete mixtures with a lower cement content and thus still achieve our environmental goals,” Zunino adds. He is convinced that LC3 will be the most widely used type of cement worldwide ten years from now.<hr><h2 id="isPasted">Reference</h2>F.

Green change in a grey industry

After a strong performance at Elon Musk&#39;s &quot;Not-a-Boring Competition&quot; in 2021,&nbsp;Swissloop Tunneling&nbsp;upgraded its award-winning tunnel boring machine. With some critical parts made by&nbsp;<a href="https://www.makerverse.ai/" rel="noopener noreferrer" target="_blank">MakerVerse</a>, an online platform for on-demand manufacturing, the team readied its powerful device for the 2023 competition in the United States.Building a safe and efficient tunnel infrastructure requires cutting-edge tunnel boring machines to excavate through soil and rock. However, high costs and demanding logistics limit the technology. Improved tunneling would help make transportation alternatives like the hyperloop a reality.To overcome those challenges, Elon Musk and his &quot;The Boring Company&quot; sponsor contests where hundreds of teams worldwide seek to build the best tunnel boring machine, with the five top teams selected to compete in person. <a href="https://swisslooptunneling.ch/" target="_blank">Swissloop Tunneling</a> is one of those teams pushing the boundaries of tunneling technology.In 2021 in Las Vegas, the team of engineering students from ETH Z&uuml;rich won the innovation and design award and finished second overall. For the 2023 competition,&nbsp;Swissloop Tunnelling&#39;s ambition was to continue its success with renewed systems in its machine.&quot;The team turned to MakerVerse to upgrade their machine with several high-quality steel connectors built to withstand extreme conditions.&nbsp;<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjg2NjQ4MTcxNTY5LTIwMjMwMjI4XzExNDYwNCAoMSkgKDIpLndlYnAiLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 577px;" class="fr-fic fr-dib"><div data-mesh-id="comp-lewo56gsinlineContent" data-testid="inline-content"><div data-mesh-id="comp-lewo56gsinlineContent-gridContainer" data-testid="mesh-container-content"><div data-testid="richTextElement">The connector (with the four holes in the center) sits at the head of the extruder and connects four different tubes. It&#39;s made with Laser Powder Bed Fusion.</div></div></div><h3>The challenges</h3>Swissloop Tunneling&#39;s machine, named Groundhog Beta, measures eight meters long, weighs 3,000 kilograms and has a diameter of 590 millimeters. Every component of Groundhog Beta must withstand burdensome workloads and high temperatures.Since its last tournament, Swissloop Tunneling has been busy upgrading and optimizing its first machine, Groundhog Alpha. Especially the erosion and liner system have been redesigned for the new machine. Therefore, some parts had to be developed within the size of a prototype in the first phase, to validate designs and test further improvements.For example, the liner system prototype was built at 1:5 scale before being scaled up to the final size. In the end, the team integrated the newly designed parts into Groundhog Beta and successfully completed its full-size version.&nbsp;One of the most critical sections of Groundhog Beta is the innovative tunnel lining system. The team integrated a polymer extrusion system into the machine to create safe and stable tunnel walls. The liner system prints a 15 mm thick tunnel wall to ensure the tunnel&#39;s structural integrity. This process uses a polymer granulate that&#39;s pumped into the tunnel through air pressure. There, the polymer gets melted via an extrusion screw. As a result, the polymers reach temperatures of up to 200 degrees Celsius and must be cooled via a 10 degrees Celsius cooling fluid.These massive temperature ranges, plus the critical importance of the entire tunnel lining system, meant Swissloop Tunneling needed extremely high-quality parts from a trusted partner. Importantly, the parts needed to be affordable and delivered in time to meet tight deadlines.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjg2NjQ4MzE0Mjc4LTIwMjMwMjI4XzEwMzkwMSAoMSkgKDEpLndlYnAiLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 310px;" class="fr-fic fr-dib">A series of machined connecting rings join different components within the tunnel lining system.&nbsp;<h3>The solutions</h3>MakerVerse, with its wide range of technologies, provided the crucial liner system prototype with several high-quality components at the needed prices.Swissloop Tunneling sourced several steel connecting rings with more than 500 mm diameters using <a href="https://www.makerverse.ai/cnc" rel="noopener noreferrer" target="_blank">CNC machining</a>. These connectors join different components within the tunnel lining system, such as the liquid cooling chamber.

In this episode, we talk about how new additives could be added to concrete to help it absorb carbon dioxide (CO2) from the atmosphere, which is a major contributor to climate change. By using these additives, concrete could become a &quot;carbon sink,&quot; which means it could potentially store more carbon than it emits, making it a more sustainable building material. This could have a positive impact on the environment and help combat climate change.&nbsp;<iframe height="200px" width="100%" frameborder="no" scrolling="no" seamless="" src="https://player.simplecast.com/b0f4970e-413e-4687-90f1-30d788ed5208?dark=false" class="fr-draggable" data-lf-form-tracking-inspected-kn9eq4roawkarlvp="true" data-lf-yt-playback-inspected-kn9eq4roawkarlvp="true" data-lf-vimeo-playback-inspected-kn9eq4roawkarlvp="true"></iframe><hr>EPISODE NOTES(0:40) - <a href="https://www.wevolver.com/article/new-additives-could-turn-concrete-into-an-effective-carbon-sink" target="_blank">New additives could turn concrete into an effective carbon sink</a><hr>As always, you can find these and other interesting &amp; impactful engineering articles on Wevolver.com.To learn more about this show, please visit our <a href="https://www.wevolver.com/profile/the.next.byte" target="_blank">shows page</a>.

<h2>FACTUREE produces a joint component for nodes of a variable grid structure for a research project at TUM</h2>The &ldquo;Kinetic Umbrella&rdquo; research project at the department of architecture at the Technical University of Munich (TUM) investigates the applicability of flexurally elastic mechanisms in the area of variable grid structures. The controlled elastic deformation of the grid bars enables spatially complex variation processes. An international collaboration with industry was launched to build a prototype for the first semi-elastic variable grid structure. TUM commissioned Online Manufacturer FACTUREE with producing the small format joint components for the nodes.One of the main focus areas of the department of architecture at the Technical University of Munich (TUM) includes the research and development of innovative building technologies. As part of a doctoral thesis on &ldquo;Elastic Mechanisms in Grid Structures&rdquo;, fundamental concepts were already developed and successfully implemented in static applications within the &ldquo;Kinetic Umbrella&rdquo; research project. The development includes methods of mechanical simu&not;lation, the morphology of elastic mechanisms, architectural and constructive approaches, as well as suitable materials.In the next step, the potential of such mechanisms for variable constructions will be investigated. For this purpose, a prototype for the first semi-elastic variable grid structure will be developed, featuring a foldable umbrella design with a diameter of eight meters.<h2 id="isPasted">Production of prototype with components from Online Manufacturer</h2>M.Sc. Jonas Schikore, civil engineer and research associate at the Technical University of Munich, explains, &ldquo;Some of the components are produced in our own workshops at TUM. However, when we reach the technical limits of our facilities, we involve third-party suppliers. This was the case in our current project in the production of aluminum extruded profiles. When producing prototypes, it is common practice to have some components made by third parties.&rdquo;For planning the prototypes, TUM uses mainly 3D models. Specialized manufacturers are often brought on board to support the process.&ldquo;In the construction sector, you always need customized components sooner or later. Our focus is on the research and development of innovative building technologies. As our developments need to account for the industrial processes in order to yield practical solutions and technologies, we are in constant contact with industry for this,&rdquo; says M.Sc. Jonas Schikore.Against this background, TUM decided to collaborate with Online Manufacturer FACTUREE, which they had learned about through an internet search, because building the prototype requires customized components. The department of architecture could easily upload 3D models in FACTUREE&rsquo;s online interface and obtained a calculation within 24 hours. Other competitors did not react to inquiries as quickly.FACTUREE is a trademark of cwmk GmbH and has an extensive production network of over 1000 manufacturing partners, mainly in the areas of CNC machining, sheet metal processing, 3D printing, and surface technology. In the &ldquo;Kinetic Umbrella&rdquo; project, the company supplies the joint component for the nodes of the variable grid structure.&ldquo;The components procured through FACTUREE are small-format joint components. The aluminum component can be attached eccentrically to GRP laminates and forms the socket for a pivot bolt. It has inner threads and is suitable for a direct friction-lock connection with the connecting component. It is optically particularly appealing due to the surface treatment,&rdquo; explains M.Sc. Jonas Schikore.<h2 id="isPasted">Fast provision times and on-time deliveries</h2>With the Online Manufacturer, TUM utilizes an especially modern form of procurement. The online network approach allows customized components to be manufactured with a high level of precision and be delivered quickly by specialized suppliers. However, FACTUREE is the only contract partner involved, being responsible for selecting the most suitable manufacturer and handling the entire process.TUM decided to have their parts provided by FACTUREE because of the convenient contact, the preparation of a timely quotation, and the reasonable delivery times.M.Sc. Jonas Schikore reports, &ldquo;We were able to lower the costs of the components after some consultations. For us, the obvious strengths of FACTUREE include the ease of transmitting data and the fast, reliable quotation. The direct personal communication and consulting was also decisive for the smooth procedure. Our contacts responded immediately to our email inquiries and telephone support was also readily available. The cooperation thus far was appraised by our employees to be positive and competent as well.&rdquo;<h2>Online Manufacturing will continue to be an option in the future</h2>In future projects, TUM will continue to rely on high-quality components and optimized costs. &ldquo;At the chair for structural design, we build prototypes and new developments on a regular basis for our research projects. With FACTUREE, we can now react quickly and efficiently, because the Online Manufacturer offers a wide production range, good prices, and fast provision times. We were very impressed with the quality of the components supplied. Delivery was on time, perceptibly easing our planning and construction process. We will turn to FACTUREE again for further needs going forward,&rdquo; concludes M.Sc. Jonas Schikore.

How do you measure the volume of a hole in the ground?If the hole is small and rectangular, it is simple. But what about the giant hole dug for the foundations of a city center skyscraper, or for a new underground train station? It will generally be irregular in all three dimensions, and very large.Accurately measuring the volume of excavation works is a little known but surprisingly contentious, time-consuming and expensive process for building companies to perform. The work calls for the services of highly paid and scarce surveyors.Now <a href="https://sodex-innovations.com/" rel="noopener noreferrer" target="_blank">Sodex Innovations</a>, a technology start-up company based in Austria, has developed a product which automates cavity measurement, eliminating the need for site visits by surveyors. This technology is quicker, more convenient, and provides more useful data than conventional surveys &ndash; and it depends for its operation on Movella&rsquo;s <a href="https://www.xsens.com/inertial-sensor-modules" rel="noopener noreferrer" target="_blank">Xsens MTi</a> technology.Excavation: a money pitHoles are big business in the construction industry. Building companies pay contractors for excavation work: the bigger the hole, the higher the fee for excavation. The material dug out of the ground &ndash; the &lsquo;spoil&rsquo; &ndash; also has a monetary value. This might be the cost to dispose of it. Or, if the spoil is a material such as gravel which can be repurposed, it has value to a customer who can buy and use it. Again, the bigger the volume of spoil, the higher the value.So measuring holes and spoil is a crucial function of any large building project. Classifying the type of material in the spoil is also essential, to determine whether it has any resale value, or requires special disposal measures.Today, surveying is the preserve of highly qualified professionals. Because of their scarcity and high levels of training and education, these professionals command high fees for their work. And since they are required to travel from site to site to perform surveys, building companies frequently have to organize their operations around the availability of a surveyor, rather than fitting surveys into building schedules.And of course any function performed by a human is subject to the risk of human error. This means that disputes over surveys are surprisingly common, adding yet more friction to the seemingly simple business of digging a hole in the ground.Ralf Pfefferkorn encountered this problem when developing a prototype for a robot excavator as a student project. Excavation appeared to be ripe with the potential for automation. So on graduation in 2017, Ralf and two colleagues, Raphael Ott and Bernhard Gantner, founded Sodex Innovations. Some five years later, Sodex gained the first customers for its fully automatic device for volumetric measurement of cavities, the SDX-4DVision system.The surveying machine: laser and camera-based technologyThe SDX-4DVision product is a system which combines high-technology laser scanners and cameras to calculate the 3D dimensions of an excavation. The accumulation of millions of measurements enables the system to build a detailed point cloud from which very accurate volumetric measurements can be calculated in real time (see Figure 1). As well as a laser scanner, the SDX-4DVision has a video camera which adds photographic documentation to the survey.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjY1NDc2NDE5NjQ4LVNvZGV4LmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 300px;" class="fr-fic fr-dib">Fig. 1: the laser scanner creates a continually updated scan of the depth and extent of a hole&nbsp;The SDX-4DVision unit is mounted on the boom of an excavator, from where it has an uninterrupted view of the ground (see Figure 2).

It also needs to constantly adjust its calculation of the laser measurements to take account of the tilt and 3D position of the boom-mounted SDX-4DVision unit relative to its resting position.These sets of real-time motion data are provided by Movella motion sensors. The Xsens <a href="https://www.xsens.com/mti-630r" rel="noopener noreferrer" target="_blank">MTi-630R</a> AHRS (attitude and heading reference system) provides acceleration, rate-of-turn and heading information so that the position of the boom relative to the chassis of the excavator can be continuously tracked.A second sensor, the Xsens&nbsp;<a href="https://www.xsens.com/mti-680g" rel="noopener noreferrer" target="_blank">MTi-680G RTK GNSS/INS</a>, provides precise geolocation data from a satellite positioning signal supported by RTK (Real-Time Kinematics) signal enhancement, giving total geolocation accuracy of &plusmn;3cm.This sophisticated hardware platform supports the operation of Sodex&rsquo;s advanced software for calculating the volume of a cavity in real time, and for displaying this information in an easy-to-use format, in real time, at the Sodex cloud computing portal.&nbsp;<iframe width="640" height="360" src="https://www.youtube.com/embed/XYEMagRvMSk?&wmode=opaque&rel=0&enablejsapi=1&origin=https://www.wevolver.com" frameborder="0" allowfullscreen="" class="fr-draggable" data-lf-form-tracking-inspected-kn9eq4roawkarlvp="true" data-lf-yt-playback-inspected-kn9eq4roawkarlvp="true"></iframe>Transforming construction business processesRalf Pfefferkorn says that the construction industry is just beginning to learn all the benefits which it can derive from implementing automated volume measurements with the SDX-4DVision. The most obvious advantage of using the SDX-4DVision is that surveying no longer requires a surveyor, with all the advantages of cost and convenience that this brings. Crucially, the Sodex technology also eliminates the risk of conflict which often arises after conventional surveys. Ralf Pfefferkorn says. &lsquo;Big property companies are starting to mandate use of the SDX-4DVision, because it provides a single, validated source of measurements, and gives a trusted basis for billing and invoicing which all parties in a construction project can agree to be bound by.&rsquo;But he says that even more value can come from the opportunity to rethink business processes. He says, &lsquo;With a surveyor, the construction project manager just gets a single snapshot in time. The difference with the SDX-4DVision is that measurements are produced continuously in real time, so project managers always know the exact status of an excavation minute-by-minute: how close it is to completion, whether some parts of the site take longer to excavate than others, and so on. So the SDX-4DVision product gives builders a completely new tool for better project management and the better design of workflows and construction processes.&rsquo;Of course, none of this would be possible if the SDX-4DVision product&rsquo;s measurements were not highly accurate, and for this, he says, Sodex has the Xsens MTi-630R and Xsens MTi-680G sensors to thank. &lsquo;The selection of the right motion sensors was a crucial part of the system design. Fortunately, we found the MTi-600 series, which gives us the right combination of high accuracy and a high output data rate, and at a price which is affordable for us and our customers. We are delighted with the performance of the devices in the SDX-4DVision.&rsquo;And there is every sign that the construction industry is delighted with the innovation of automated volumetric measurement, a sure sign that Sodex has a successful and exciting future ahead of it.

Replacing today&rsquo;s cement is one of the hardest challenges on the journey to a safe climate with zero emissions. There are many options to make cement with reduced emissions, mainly based on mixing new reactive cement (clinker) with other supplementary materials. However, until now, it has not been possible to make the reactive component of cement without emissions. The new invention achieves this for the first time within the parameters of established industrial processes.The inspiration for Cambridge Electric Cement struck inventor Cyrille Dunant, when he noticed that the chemistry of used cement is virtually identical to that of the lime-flux used in conventional steel recycling processes. The new cement is therefore made in a virtuous recycling loop, that not only eliminates the emissions of cement production, but also saves raw materials, and even reduces the emissions required in making lime-flux.The new process begins with concrete waste from demolition of old buildings. This is crushed, to separate the stones and sand that form concrete from the mixture of cement powder and water that bind them together. The old cement powder is then used instead of lime-flux in steel recycling. As the steel melts, the flux forms a slag that floats on the liquid steel, to protect it from oxygen in the air. After the recycled steel is tapped off, the liquid slag is cooled rapidly in air, and ground up into a powder which is virtually identical to the clinker which is the basis of new Portland cement. In pilot-scale trials of the new process, the Cambridge team have demonstrated this combined recycling process, and the results show that it has the chemical composition of a clinker made with today&#39;s process.The new cement was invented as part of the large multi-university <a href="http://www.ukfires.org/" target="_blank">UK FIRES</a> programme led by Professor Allwood, which aims to enable a rapid transition to zero emissions based on using today&rsquo;s technologies differently, rather than waiting for the new energy technologies of hydrogen and carbon storage. Invention of the cement has been rewarded with a new research grant of &pound;1.7m from EPSRC, to allow the inventors to collaborate with Dr Zushu Li at Warwick University and Dr Rupert Myers at Imperial College, to reveal the underlying science behind the new process. The new grant will fund an additional team of researchers, to probe the range of concrete wastes that can be processed into Cambridge Electric Cement, evaluate how the process interacts with steel making, and confirm the performance of the resulting material.Professor Allwood said &lsquo;If Cambridge Electric Cement lives up to the promise it has shown in early laboratory trials, it could be a turning point in the journey to a safe future climate. Combining steel and cement recycling in a single process powered by renewable electricity, this could secure the supply of the basic materials of construction to support the infrastructure of a zero emissions world and to enable economic development where it is most needed.&rsquo;

Podcast: Green Infrastructure For A More Efficient Future

This is the fifth article in a&nbsp;<a href="https://www.wevolver.com/article/challenges-and-trends-in-connectivity-technologies-for-smart-manufacturing/" rel="noopener noreferrer" target="_blank">6-part series</a>&nbsp;featuring the connectivity technologies that are enabling the Industrial IoT revolution. The series introduces and explains the applications of wired and wireless connectivity technologies in various industries. This series is sponsored by&nbsp;<a href="https://www.wevolver.com/profile/mouser.electronics" rel="noopener noreferrer" target="_blank">Mouser Electronics.</a>&nbsp;Through its sponsorship, Mouser Electronics shares its passion for technologies that enable the continued sustainable growth of Industrial IoT.<h2 dir="ltr">Introduction</h2>Connectivity technologies such as the ethernet, optic fiber, cellular networks, and wireless radio have made their way to almost all industries today, and construction is no exception. By embracing this digital transformation, it can be ensured that construction-related activities can take place safely, rapidly, efficiently, and reliably.This article focuses on the applications of connectivity technologies in the construction industry. We explain what these technologies are and how they can be leveraged on-site for carrying out the construction seamlessly. But before we get to that, let&rsquo;s take a look at a real-life example explaining how connectivity technologies at construction can save the day.<h2 dir="ltr">Connectivity on the construction site</h2>Consider a situation where a 2.7 metric ton Air Conditioning (AC) unit needs to be placed on the roof of a one-story building with the help of a crane.During this operation, the crane operator sitting in a climate-controlled cab watches a flat-screen monitor tracking critical data, such as load on the boom and its extension. Suddenly, the concrete under the crane&rsquo;s left front outrigger cracks while the AC is suspended over the roof. The monitor shows 77 metric tons of load on that outrigger. But someone verifies that the outrigger is not sinking into the ground.&nbsp;Even without a direct line of sight to the rooftop area where the load will rest, the crane operator can see the landing zone through a video feed from a boom-mounted camera. The crane is equipped with fail-safe switches that prevent the operator from moving the load in any direction that is beyond the crane&rsquo;s operational limits.&nbsp;<div class="fr-img-space-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjQyNDM1NTI4MjM4LWxpZWJoZXJyLWxyLTE1MDAtY3Jhd2xlci1jcmFuZS1zdGFnZS0wMS0xOTIwLTEwODAuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 300px;" class="fr-fic fr-dib">Figure 1: Connectivity on the construction site makes it possible to operate even without a direct line of sight. Image credit: Liebherr.</div>These switches are controlled by an onboard computer that continuously recalculates limits based on changing load and position sensor data. The operator remains in constant radio contact with a crew on the roof. Other than a crack in the concrete, the AC installation goes forward without a hitch.This is just one example of how modern construction operations depend on different types of data collected and processed in real-time. Data is rapidly becoming the lifeblood of greater safety, efficiency, and precision at the connected construction site.<h2 dir="ltr">Applications of connectivity technologies in connected construction</h2>When it comes to applications of connectivity technologies, imagination is the only limit to what we can hope to have. Out of the numerous possible applications of connectivity at the construction site, here are some of the most prominent ones.<h3 dir="ltr">Precision guidance and operation of construction equipment</h3>Bulldozers have sensors built into their buckets to detect their horizontal and vertical positions. These sensors, combined with highly accurate Global Positioning System (GPS) data, are used for precision earth movement and grading on a construction site.&nbsp;These systems significantly improve efficiency and accuracy by enabling operators to see their location in real-time and set limits on how much of the earth is moved within the site. Similar controls are found in other kinds of excavation equipment.&nbsp;Even passive equipment, such as dumpsters for construction debris, come equipped with sensors that detect and signal when the bin is full so that it can be hauled off and replaced without interrupting construction operations.&nbsp;<h3 dir="ltr">Drones</h3>Before the introduction of drones and other Unmanned Air Vehicles (UAVs) in construction, data was collected manually on foot at the site. This was the only way to monitor and track the progress of the construction. Things have improved a lot since then.<div class="fr-img-space-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjQyNDM1NjQwODg3LW1vdXNlciA1IGJvZHkuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 300px;" class="fr-fic fr-dib">Figure 2: Drones and remote surveillance makes it possible to visit tough-to-reach areas or areas with limited visibility.</div>Radio Controlled (RC) drones are used to survey sites and inspect structural elements that would be difficult or dangerous for human inspectors to reach. They operate reliably in a variety of different climatic conditions and stream live video feeds for carrying out observations.<h3 dir="ltr">Autonomous vehicles</h3>Some construction sites deploy autonomous vehicles, such as driverless excavation equipment, that can be pre-programmed or remotely operated to perform precision work with fewer human operators. These devices are controlled through cloud-based applications and depend on internet connectivity, GPS data, location data from sensors, and proximity data from cameras. The data coming from all these sources is processed in real-time for collision avoidance and to prevent the equipment from injuring people.&nbsp;<h3 dir="ltr">Asset tracking</h3>Inexpensive Radio-Frequency Identification (RFID) tags, which communicate with receivers on a mesh network, help identify and track employees and equipment on a construction site. Receivers log RFID tags every time they pass through specific locations equipped with tag readers, enabling site managers to track tools and monitor the locations of trucks and other construction equipment.&nbsp;<div class="fr-img-space-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjQyNDM1ODA2ODIyLWRlbGFwLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 300px;" class="fr-fic fr-dib">Figure 3: RFID tagging is an effective solution to track the movement of people/equipment. Image credit: Delap.</div>RFID is also used to monitor and schedule the movements of equipment, such as dump trucks loading and unloading between different locations. RFID tag data is captured each time a truck drives by an RFID receiver, and that data is tracked in a database. The technology also helps keep people safe&mdash;for example, by triggering alarms if anyone goes near a hazard, such as an open elevator shaft.&nbsp;<h3 dir="ltr">Equipment monitoring and predictive maintenance</h3>Control modules continuously read data from various sensors within vehicles. Limits and triggers can be set to notify operators automatically of potential issues. These sensors also enable operators to perform preventative maintenance without impeding construction progress.<h2 dir="ltr">Ensuring signal integrity in connected construction</h2>Connected construction uses data for greater safety and efficiency in construction operations. Without that data, employees could be at greater risk, equipment might not operate effectively, and contractors incur increased maintenance costs and even work stoppages. Connected machinery and asset tracking are major factors that enable construction operations to continue round the clock in all but the most extreme weather conditions.The key to data-intensive operations such as connected construction is reliable data connectivity. If data and signal connectivity are lost, construction stops. Construction sites are harsh environments, however, and that is the challenge for engineers who design electronic construction equipment or control systems that go into construction machinery. Construction sites are unfriendly to electronic components, computers and controllers, radio transmitters and receivers, network gear, surveying and monitoring devices, and all the data-intensive equipment widely used in today&rsquo;s construction operations.To ensure data integrity and uninterrupted communications, equipment must be designed with the right connectors for the application. In harsh construction environments, poor connections are the primary cause of communications and data interruptions&mdash;the types of interruptions that can halt an operation. Connectivity technologies should come with the following features for smooth operation:<h3 dir="ltr">Support for high bandwidth</h3>High bandwidth is important because connected machinery generates enormous amounts of data that real-time control systems must receive, process, and act on. The crane moving a three-ton AC unit to a roof collects and processes data from dozens of sensors critical for precision control of its heavy load while at the same time streaming multiple video feeds. Drones, too, stream video while receiving command and control signals. RF and data connectors used in construction equipment must support high-bandwidth and low-latency connections, especially where timing is critical.<h3 dir="ltr">Ruggedized connections and Ingress Protection rating</h3>Construction sites subject electronic components to dust, water, oil, and mechanical stress. To assure data integrity in these environments, connectors should be made with stainless steel or single-piece brass, with appropriate plating for the application. Single-piece connectors can withstand a higher degree of abuse and are a lot less likely to break if they are run over by some construction equipment.<div class="fr-img-space-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjQyMDg2OTIzNzY1LUFydGljbGUgNC5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 300px;" class="fr-fic fr-dib">Figure 4: Sealed and ruggedized connectors by Amphenol are the perfect fit for challenging environments. Source: Mouser/Amphenol</div>Sealed connections offer protection against dust, moisture, chemicals and prevent foreign materials from shorting or damaging sensitive electronic components. Connectors used in construction should at least be rated with IngressProtection &nbsp;67 (IP67). Special plating on brass connectors might be required in certain applications, such as connectors on equipment used in marine environments.<h3 dir="ltr">Compatibility with widely used standards</h3>Controllers and devices used for precision control of heavy equipment and autonomous vehicles should be ruggedized, with high-bandwidth connections that conform to Fachkreis Automobil (FAKRA) automotive standards. This ensures that they remain compatible with other vehicular systems while maintaining a high degree of protection.<h3 dir="ltr">Lightweight and compact</h3>Connectors for RFID receivers, laptop computers, remote measuring equipment, and handheld portable devices should be lightweight, low profile, and weatherproof. Weight is a particular challenge in drones. Connectors for drones should be in miniature and ultra-miniature formats; they should be weatherproof and conform to at least the IP67 standard.<h2 dir="ltr">Conclusion</h2>Connected construction only works with good connectivity. The most successful device designs for construction environments use components that ensure consistent, reliable communications. By staying connected, construction operations can maximize personal safety and operational efficiency.&nbsp;This article was initially published by Mouser and Amphenol in an <a href="https://www.mouser.com/news/Amphenol-iiot-revolution/amphenol-Industrial-Iot-ebook.html" target="_blank">e-magazine</a>.

Assuring Signal Integrity in a Connected Construction Environment

A smart building uses technology to obtain data. The data is then used to enable automatic, efficient, and economical use of resources while maintaining a safe and pleasant environment for occupants.&nbsp;Typically, a smart building is a “new build”, but the term can also apply to legacy buildings retrofitted with smart technology. In either case, Internet of Things (IoT), building management systems, and artificial intelligence are used to control and optimize the performance of the building. This includes:<ul><li>Energy efficiency and sustainability</li><li>Occupancy utilization</li><li>Environmental optimization</li><li>Security</li><li>Health and Safety compliance</li></ul>In this article, we showcase 5 smart buildings that use technology in different ways to the same end: sustainability, productivity, and wellbeing.<h2>#1 - The Crystal, London</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1639917600033-The+Crystal.jpg" style="width: 766px;" class="fr-fic fr-dib"><a href="https://www.thecrystal.org/" target="_blank">The Crystal</a> is located in London's Green Enterprise District and became the first building to achieve&nbsp;<a href="https://www.breeam.com/" target="_blank">BREEAM</a> Outstanding and Platinum LEED sustainability rankings when it opened in 2012.The building generates around&nbsp;<a href="https://www.gazprom-energy.co.uk/blog/how-smart-buildings-work-a-complete-guide-with-examples/" target="_blank">70% less CO2</a> than similar buildings through a combination of rainwater harvesting, black water treatment, solar heating, and automated building management systems.Key features of the building include:<ul><li>It is a 100% electric building, around 20% of which is generated by the 1580 m2 of solar photovoltaic roof panels that cover two-thirds of the roof</li><li>Ground source heat pumps that supply virtually all of the building's heating and most of its cooling. By using 100% natural heat sources, the building receives no heating bill.</li><li>A sophisticated building management system that monitors every all electricity usage</li><li>Self-shading facades that use high-performance solar glass to allow around 70% of visible light through each window but only about 30% of the solar energy</li><li>A lighting control system that manages all lamps for optimized electricity consumption</li><li>A window control system to allow air in from outside during hot weather, which automatically closes windows and puts an interior ventilation system during extreme weather.</li></ul><h2>#2 - DPR Construction Net-Zero Energy San Francisco Regional Office</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1639917680977-DPR.jpg" style="width: 766px;" class="fr-fic fr-dib">When the DPR regional office in San Francisco was being designed, its goal was “<a href="https://www.resonai.com/blog/4-best-intelligent-buildings" target="_blank">to incorporate cost-saving and environmentally-friendly features</a>” that would achieve net-zero energy certification and serve as a ‘living lab’ to test the newest and most intelligent energy-efficient products on the market.As a result, it uses many smart features, including:<ul><li>Net-Zero Building (NZEB) Certification. NZEB means that the total amount of energy used yearly by a building is equal to or less than the amount of energy created onsite through the use of innovative technologies and renewable power generation</li><li>300 photovoltaic panels to generate renewable energy</li><li>Rooftop solar thermal water heating system</li><li>Electrochromic windows</li><li>8 solar-powered, automated skylights over an atrium</li><li>Ultra-energy efficient ceiling fans</li><li>3 living walls and a living wine bar</li><li>Use of reclaimed redwood and Douglas fir</li><li>Ultra-low flow and flush plumbing fixtures</li></ul><h2>#3 - The Edge, Amsterdam</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1639917697995-The+edge.jpg" style="width: 766px;" class="fr-fic fr-dib"><a href="https://edge.tech/developments/the-edge" rel="noopener" target="_blank">The Edge</a>, in the Zuidas business district in Amsterdam, has been described by many as&nbsp;<a href="https://www.bloomberg.com/features/2015-the-edge-the-worlds-greenest-building/" target="_blank">the smartest building in the world</a>.It has perhaps the world's largest deployment of IoT sensors in a single location (28,000), with the collected data used to adapt the building to meet real-time requirements. For example, areas can automatically be shut down or closed when no one is present, thereby saving energy.Other smart features in The Edge include:<ul><li>Sensor data for motion, light, temperature, and humidity</li><li>Solar panel roof</li><li>Energy reuse – excess ventilation air from offices is reused to air-condition the atrium space</li><li>Rainwater reuse – collected rainwater is used to flush toilets and irrigate the green terraces in the atrium and other garden areas surrounding the building</li><li>Thermal energy storage – Two 129m deep wells reach down to an aquifer, allowing thermal energy differentials to be stored deep underground.</li><li>An employee app, combined with data from sensors, provides:<ul><li>personalized schedules</li><li>access control around the building</li><li>assistance finding a workspace or parking place</li></ul></li><li>Adjust the office temperature has 98.4% sustainability rating from&nbsp;BREEAM</li></ul><h2>#4 - Allianz Arena, Munich</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1639917715477-Allianz.jpg" style="width: 766px;" class="fr-fic fr-dib">The&nbsp;<a href="https://allianz-arena.com/en" target="_blank">Allianz Arena</a> located in Munich, Germany is a football stadium with a capacity of 70,000 spectators.It is nicknamed the Inflatable Boat (Schlauchboot) and has a unique lighting feature. The arena’s exterior, through the control of 3,000,000 lights, can change color e.g. have rainbow colors during Pride month.Internally, the stadium uses the latest smart technology to provide a pleasant and safe environment for both the football club and its supporters. For example:<ul><li>sensors and cloud-based analytics to monitor the health of the grass on the pitch if the temperature is too cold the grass will be heated and if the ground is too dry it will be watered.</li><li>acoustic cameras with sound mapping software are used to study how fans respond throughout the game</li></ul>The external lighting system is energy efficient and saves approximately&nbsp;<a href="https://naylor.iotm2mcouncil.org/bayall" target="_blank">60 percent on electricity and 362 tons of CO2 per year</a> compared to other similar facilities.<h2>#5 - Leadenhall Building, London</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1639917740585-5.jpg" style="width: 766px;" class="fr-fic fr-dib">The&nbsp;<a href="https://www.theleadenhallbuilding.com/" target="_blank">Leadenhall Building</a> is London’s second-tallest building.Known as the “cheesegrater”, owing to its shape, extensive use of IoT technology was made during its construction. RFID-based data tags helped builders and construction companies to track the location of components and installation.This enabled around 83% of the construction to be completed off-site, streamlining the building process, improving project management and control of the building works.The 48-story building includes many smart features, including:<ul><li>293 energy meters on-site to monitor the use of lighting</li><li>Intelligent and state of the art lifts that can go from the ground floor to the top floor in 30 seconds</li><li>low-flow water fixtures and fittings</li><li>external glazing which includes vents every seventh floor to let air circulate freely, reducing the need for AC systems</li></ul><h2>Conclusion</h2>These five examples demonstrate how buildings can integrate IoT and smart building technology in many different ways.From the initial design and construction, where RFID tagging was used to track building components through renewable energy production and sustainability, to intelligent working and sporting environments, energy savings, recycling of air and water, and access control smart buildings are now on the rise.As the world&nbsp;<a href="https://www.disruptive-technologies.com/blog/is-this-our-last-chance-to-control-climate-change" target="_blank">continues to fight against climate change</a> and recover from the COVID-19 pandemic, there is a greater need for buildings to become more energy-efficient and to lower their CO2 footprint. In addition, after millions of employees successfully adapted to working from home, the office workspace needs to be more wellness-aware in order to attract workers back.Intelligent buildings are here to stay.

A smart building uses technology to obtain data. The data is then used to enable automatic, efficient, and economical use of resources while maintaining a safe and pleasant environment for occupants.
